S-series Broadlighters are high-power, high-stability, low-coherence, broadband AC powered SLD light sources. They are based on Superlum's high-power (HP) SLD modules. The most high-power Broadlighters are equipped with appropriate polarization-insensitive fiber-optic isolators that protect the SLD modules from being damaged by optical feedback. All the light sources have two operating modes: the High Power mode and the Low Power mode. During normal operation, the High Power mode of the Broadlighter is always employed, whereas the Low Power mode is intended for safe alignment of optical components and circuits in the customer's optical system during the set-up process. The devices are developed for optical test and measurement applications including:

• Optical coherence tomography
• Characterization of optical components
• Optical fiber metrology
• Optical measurements
